Abstract (en)
A method for data synchronization of multiple nodes includes: receiving, by a master node in at least one master node in the multiple nodes, a write operation submitted by an application program; packaging, by the master node, at least one data change log corresponding to the write operation into a block generated by the master node, and signing the block; broadcasting, by the master node, the block to other nodes in the multiple nodes after signing the block; reading, by at least one synchronous node in the multiple nodes, the at least one data change log in the block, and executing at least one data change operation corresponding to the at least one data change log in the block; and determining, by at least one node in the multiple nodes, an operation state of the block.
